INSTALLGRUB(8) Maintenance Commands and Procedures INSTALLGRUB(8)

NAME

installgrub - install GRUB in a disk partition or a floppy

SYNOPSIS

/sbin/installgrub [-fm] stage1 stage2 raw-device

DESCRIPTION

The installgrub command is an x86-only program. GRUB stands for GRand
Unified Bootloader.


installgrub installs GRUB stage 1 and stage 2 files on the boot area
of a disk partition. If you specify the -m option, installgrub
installs the stage 1 file on the master boot sector of the disk.

OPTIONS

The installgrub command accepts the following options:

-f
Suppresses interaction when overwriting the master boot sector.


-m
Installs GRUB stage1 on the master boot sector interactively.
You must use this option if Solaris is installed on an extended
FDISK or an EFI/GPT partition.

OPERANDS

The installgrub command accepts the following operands:

stage1
The name of the GRUB stage 1 file.


stage2
The name of the GRUB stage 2 file.


raw-device
The name of the device onto which GRUB code is to be
installed. It must be a character device that is
readable and writable. For disk devices, specify the
slice where the GRUB menu file is located. (For Solaris
it is the root slice.) For a floppy disk, it is
/dev/rdiskette.

EXAMPLES

Example 1: Installing GRUB on a Hard Disk Slice

The following command installs GRUB on a system where the root slice
is c0d0s0:


example# /sbin/installgrub /boot/grub/stage1 \
/boot/grub/stage2 /dev/rdsk/c0d0s0

Example 2: Installing GRUB on a Floppy

The following command installs GRUB on a formatted floppy:


example# mount -F pcfs /dev/diskette /mnt
# mkdir -p /mnt/boot/grub
# cp /boot/grub/* /mnt/boot/grub
# umount /mnt
# cd /boot/grub
# /sbin/installgrub stage1 stage2 /dev/rdiskette

FILES

/boot/grub
Directory where GRUB files reside.

WARNINGS

Installing GRUB on the master boot sector (-m option) overrides any
boot manager currently installed on the machine. The system will
always boot the GRUB in the Solaris partition regardless of which
fdisk partition is active.
